It was 1983 and my wife rented the movie Blade Runner on VHS – at that time video rental stores were relatively new and renting a movie required advance reservations. To be honest, I didn’t know much about the movie prior to viewing. I assumed it would be just another flashy sci-fi movie with ridiculous sci-fi technology and crazy impossible physics. However, what I actually experienced was a movie that changed how I viewed science fiction as a vehicle for serious ideas.
One of the first things that caught my eye was not the flying cars or the replicants, but the engineering. Not the fictional engineering, but the actual craftsmanship that created the entire world of Blade Runner. As an engineer in the aerospace field, I have always been interested in how things are built, and the amount of attention to detail and craftsmanship that went into building this world was obvious. For example, the miniature work alone… wow, I can only imagine the number of hours that must have gone into those cityscapes. You can see the texture of the buildings, the dirt on them, the way the light reflects off of surfaces that appear to be three-dimensional.
Don’t get me wrong, the science in Blade Runner is purely fictional. Creating humans genetically engineered to be perfect human replicas? Unlikely. Flying cars that somehow function flawlessly in a crowded urban environment without crashing? Ridiculous. Traffic control systems? Even more absurd. Here’s what Ridley Scott seems to understand that most sci-fi filmmakers fail to grasp; the technology itself doesn’t matter. It is what the technology represents for the people who live with it that matters.
As an engineer I spent years working on developing propulsion systems for satellites. Let me tell you, engineering is a mess. Nothing works perfectly and nothing lasts forever and you’re always patching and making do to just keep systems operating. This is exactly what Scott’s 2019 Los Angeles feels like – a world where amazing technologies exist along side rot, decay, and the miraculous and the mundane exist together. The Tyrell Corporation’s pyramid may hold godlike genetic engineering abilities, however the streets below are littered with trash and rain.
This attention to worn, lived in details is why Blade Runner feels so realistic compared to other movies with 10 times the budget. I’ve worked on projects where we’d spend months perfecting a single part, focusing on the minute details of tolerance and stress factors that the user would never even see. Scott’s production team had the same level of attention to craft. Each surface in the movie tells a story about how it’s been used, maintained, or neglected.
However, it wasn’t until I had multiple viewings of the movie that I realised how much the film explores memory and identity. Roy Batty’s “tears in rain” monologue resonates so much more when you’re in your 70’s and watching friends from your engineering days die. All the late nights spent debugging satellite control systems, the pride in launching satellites successfully, the frustration of unsuccessful launches… In 50 years, will anyone remember any of this? Hell, half the satellites I worked on are probably space debris by now.
The replicants’ four-year lifespan, to me initially appeared to be simply an arbitrary plot element when I first saw the film. However, it is a brilliant condensation of human mortality. We all have limited time, and we all wrestle with questions about whether our experiences matter, whether we’ll be remembered, and whether we were truly alive or just pretending to be.
Roy Batty dying on the rooftop, holding a dove… That’s not just science fiction melodrama. That’s existential fear made tangible.
Philip K. Dick had an understanding of consciousness and identity that many hard sci-fi writers do not comprehend. You can have the most accurate science imaginable, but if you don’t question what it means to be human, you’re simply writing long, detailed technical manuals. Blade Runner takes Dick’s paranoid questioning of reality and places it in a world that feels tangible, immediate, and frightening.
I’ve probably seen Blade Runner 30+ times over the past few decades, and it continues to reveal new layers. The directors cut removed Deckard’s narration, which greatly improved the film… Show, don’t tell, particularly when you have visuals as strong as those presented. The final cut refined things even further. It is extremely rare for a director to receive the opportunity to refine their vision on multiple occasions, and Ridley Scott maximized each opportunity to eliminate unnecessary elements.
When Blade Runner 2049 was released in 2017, I was extremely skeptical. Most sequels to beloved films are cash grabs that completely miss the essence of the original film. However, Denis Villeneuve somehow managed to create a sequel that honored Scott’s vision, while also expanding upon it in meaningful ways. The visual design continued to present a tactile representation of reality, and the themes expanded upon the original themes, rather than simply retreading old ground. While I still prefer the original film – there’s something about that 80’s analog aesthetic that cannot be recreated – 2049 demonstrated to me that thoughtful science fiction cinema is not dead.
My concern with modern sci-fi filmmaking is the reliance on digital effects. Everything is too clean, too perfect, too obviously generated by computers. Blade Runner’s Los Angeles appears to be a place that you could walk through and smell the exhaust of the pollution. Modern filmmakers likely would generate the entire city in a computer, and although it would be visually stunning, it would also lack the tangible quality of the original film. There is no replacement for physical models and practical lighting when you want the audience to believe in your world.
Blade Runner has had an enormous influence on science fiction films that followed it, although not always for the better. Too many filmmakers copied the visual style of the film without appreciating the craftsmanship behind the visual style and the thematic depth of the film. The dark city with neon lights became a cliche, however the emotional resonance of the darkness of Blade Runner was lost in the countless, shallow imitations.
Forty years in engineering has taught me to appreciate when someone takes the time to do things correctly, whether it is a propulsion system or a piece of cinema. Clearly, the people involved in creating Blade Runner were engineers themselves, who spent the time to sweat every detail, and who recognised that lasting art involves both technical excellence and emotional truth. Combining these two elements is much less common than one would expect, in engineering or filmmaking.
Watching Blade Runner again recently, I am amazed by how prophetic some of the themes in the film have proven to be. The increasing power of corporations, the degradation of the environment, and the increasingly blurred lines between what is artificial and what is authentic are not issues of a far-off dystopian future. We may not have replicants, but we are indeed struggling with questions of what it means to be human in the face of increasing automation and artificial intelligence.
This is what good science fiction does; it uses imaginary technologies to explore very real concerns of humanity. Blade Runner succeeds not because its science is correct (it isn’t), but because it asks timeless emotional and philosophical questions. After forty years, it still feels like a message from a possible future we should probably attempt to avoid.
